Individual-Based-Model used in \"Population context matters: predicting effects of metabolic stress mediated by food availability and predation with an agent- and energy budget-based model\"

Maxime Vaugeois, Valery E Forbes, Paul A Venturelli, Chiara Accolla & Stephanie L Hummel
This is the programming software code of the model developed to investigate the population-level impacts of a hypothetical, sublethal stressor that can affect an individual’s metabolism (growth, reproduction, maintenance, or assimilation) in systems in which population size is controlled by different combinations of food availability and predation pressure. The life cycle of fathead minnow (Pimephales promelas) is describe through their metabolism, using the Dynamic Energy Budget theory (DEB) and we represent the populations through an...

Data from: Resource constraints highlight complex microbial interactions during lake biofilm development

Abstract 1. This study evaluated how the availability of nutrients and organic carbon interact to influence the associations between autotrophic and heterotrophic microorganisms during lake biofilm development. Considering that decomposers are often better competitors for nutrients than producers in aquatic environments, we hypothesized that heterotrophs would outcompete autotrophs for available nutrients unless heterotrophs were limited by organic carbon provided by autotrophs. 2. To test our hypothesis, we evaluated autotrophic (algae) and heterotrophic (fungi, bacteria) biomass...
